A drill bit is a tool used to cut or crush rock. With rotary drilling, a hole is drilled by the continuous turning of a drill bit. The drill bit is the mechanism that cuts into the ground layers to reach the gas deposit or to cut a core sample.

A tricone bit is a mechanical drill bit located in the bottom hole assembly. The bit cuts away the surface of the rock being drilled through rotation and mechanical friction caused by the teeth of the bit.

Drill bits are designed to drill holes in a variety of different common materials. These include different types of wood, metal, plastic, ceramic tile, porcelain and concrete. Drill bits made for steel, aluminum, copper, cast iron, sheet metal, fiberglass, brick, vinyl flooring and more are also available.

Tricone bits are used in general to drill a wide variety of rocks, from soft to extremely hard, while PDC bits can drill various sorts of formations, especially at harsh environments.
